The Kare Kano manga actually dropped the ball near the end, when it became a straight out drama. And then the mangaka had Asaba marrying Yukino and Arima's daughter years later.

I still like Gainax. They're different now than they used to be, though--but I don't think they're necessarily a "bad" company now either. I do yearn for their freewheeling maverick days when they had ambition to elevate the artform both in terms of animation and storytelling. They're still great for their maverick animators, but they don't really try to do "big" anime about "big" themes anymore. Just a bunch of really talented animators doing shows for otaku.
I don't think the Gainax of the 80s could exist today though. I read a recent interview by one of Gainax's old staff members and he said that in today's anime industry, making something like Wings of Honneamise would be impossible, and that it's a miracle that it even exists.
I don't need to like a studio to respect them. For example, I love a lot of Capcom video games, but from all I've heard they've been a really shitty video game company when it comes to how they treat their employees.
